Tile-cutting machine



Patented Mar. 18, 1930 UNITED STATES PATENT OFFICE OTTO WALTER, OFPERRYSVILLE, INDIANA TILE-CUTTING MACHINE Application filed October 3,1927. Serial No. 223,598.

The object of this invention is the making of a machine for practicallyand successfully cutting roof tile and the like, such as concrete tile,clay tile or tile made of any material of the same general character.

Another object of said machine is to minimize or avoid waste as by thismachine both parts of a cut tile is capable of use, one on the hip ofthe roof and one in the valley,

whereas heretofore only one part has been capable of use, the otherbeing in broken pieces that had to be thrown away.

Another object of the invention is to provide such a machine as a commonlaborer can operate successfully, because of its simplicity, and stillanother object is to provide a very smooth cut surface instead of aragged broken edge.

The features of the invention will be understood from the accompanyingdrawings and the following description and claims.

In the drawings Fig. 1 is a vertical transverse section of the machineon the line 11 of Fig. 2. Fig. 2 is a longitudinal vertical section ofthe machine on the line 22 of Fig. 1.

The machine is provided with a frame 10 substantially rectangular inform and having a table 11 with a'metallic surface 12, longi- 3 tudinalbars 13, 14 and 15 and cross bars 16,

'17, 18 and 19.

A rotary cutter is mounted on a shaft 20 mounted transversely in themachine in bearings 21 and 22 mounted on the bars 13 and 14 and drivenby a pulley 23 secured thereon. The rotary cutter is mounted on theinner end of the shaft 20 and consists of a hub 25, a metal disk 26 andan annular emery cutter 27 secured on the periphery of said disk 26, asshown. The hub 25 of the cutter is mounted on a reduced portion 28 ofthe shaft 20 and clamped thereon by the nut 29.

The rotary cutter is mounted so that the upper portion thereof willproject through a slot 30 in the table 11, as shown, much like rotarysaws are mounted.

The water tank is secured in the frame between the bars 14 and 15 andbelow the table 11, so that the cutter will operate therein, as shown.This tank is filled about half full .the water deflector.

of water, that is, so that the water will extend up almost to the hub ofthe cutter. This is for the purpose of keeping the cutter wet and alsokeeping the tile wet while it is being out.

It is noted that the main part of the frame composed of the parts 10,13, 14, 15, 17'and 19 is stationary and the water tank 35 is mountedtherein and extends appreciably higher than said stationary frame, asshown in Fig. 1, and it also extends from front to rear orlongitudinally of said frame. The bearings of the cutter are mounted onthe sta tionary part of the frame as seen also in Fig. 1. The upper partof the frame consisting of the table 11 and cross bars 16 and 18 arehinged at the rear end of the machine on cross bar 17 so that its frontend can be lifted and said upper part of the frame tilted upward by theworkmen standing at the front end of the machine, and at that end thetable projects as shown in Fig. 2. This furnishes easy access to thewater tank and to the cutter.

Roof tile is generally cut diagonally to adapt the portions thereof tothe hip or the valley of the roof. The tile is placed upon the table 11and fed to the cutter much in the same way as wooden boards are hand fedto rotary saws, the cutter turning in the direction indicated by thearrow in Fig. 2. The cutting portion 27 of the cutter, the emeryportion, is usually about one-fourth inch thick so that it cutssubstantially a onefourth inch kerf. V

A water deflector 40 is mounted above the cutter substantially as shown,by means of an arm. 41 that is secured by bolts to the frame bar 16 atthe rear end of the hinged part of p the frame and extends forwardly asshown in Fig. 2. The water deflector has an upper wall concavely curvedlongitudinally and forwardly of the machine and the cutter, and it hasside walls 42 parallel with each other and extending downward to .apoint slightly below the upper edge of the cutter, so that the upperedge of the cutter, in a sense, runs in Also the deflector is turneddownwardly and somewhat rearwardly in the form of a lip at the front endthereof, as seen in Fig. 2. Therefore the deflector is such as toconcentrate and direct the water on the cutter and prevent water beingthrown too far forward against the workmen by the cutter. Since theperiphery of the cutter is made of emery or like material and istherefore relatively thick and porous, as distinguished from a metalcutter, it will throw and direct an ample quantity of water upon thetile which is located on the table in front of the cutter. lVhile it isbeing cut thus both the cutters and the tile are kept water-soakedsufiiciently and amply and the workman is' i to the cutter.

The table 11 is depressed at 43 near the cutter slot 30 and on each sidethereof, as shown in Fig. 1, and there are also a number of drainageholes 44 in said depressed portion. This is for the purpose offacilitating the drainage or return of the water that is carried upwardby the cutter and deflected by the water deflector l0. There is also asplash plate 45 secured to the under side of the table 11 around saidperforations and depression and extends into the upper end of the tankfor guiding the water back to the tank and preventing the watersplashing out over the top of the tank.

lVater is required to keep the cutter and tile wet and dustless. Drytile is so very hard that it is impractical to cut it unless it issoftened by being saturated with water. The water also facilitates thecutting of the emery and particularly keeps it from heating and prolongsits life. When the hinged upper portion of the frame is moved upward andbackward by the workmen lifting the front part thereof, it carries withit both the deflector l0 and the splash plate 45, which is securedthereto. This is permitted by ample clearance being provided between thesplash plate 40 and the wall of the water plate 35, as shown in Fig. 2.

The invention claimed is:

1. A machine for cutting tile and the like having a stationary frame, awater tank mounted therein with its top open, a vertically disposedrotary cutter having its periphery formed of emery and the like andmounted in the machine so that the lower portion thereof will run in thewater in the tank and the upper portion thereof will extend above thetank, an upper portion of the frame including a table which portion ishinged at the rear end to the stationary portion of the frame andarranged so that the front end thereof may be lifted and tilted upwardand backward and the table thereof being provided with a slot throughwhich the upper part of the cutter projects, and a water deflectorsecured at the rear end of said up per part of the frame and extendingforward and free above the cutter with the sides and front end thereofextending below the upper edge of the cutter for concentrating the waterwhich is thrown upward against said reflector down on the cutter,substantially as set forth.

2. A machine for cutting tile and the like substantially as set forth inclaim 1 with the water tank extending above the stationary part of theframe, and a splash plate secured to the under side of the table andextending down into the water tank with suflicient clearance betweensaid splash plate and the water tank to permit the tilting upward andbackward of the upper part of the frame including the table and waterdeflector substantially as set forth.

3. A machine for cutting tile and the like including a slotted table, avertically disposed rotary cutter mounted below the table with its upperand operating portion extending through the slot in the table, a watertank located below the table, the lower portion of the cutter running inthe water whereby water will be carried up by the cutter for wetting thecutter and tile, and an overhanging combination guard and waterdeflector, mounted above the table and cutter with its sides and endsextending below the upper edge of the cutter for deflecting the waterwhich is thrown upward against said deflector down on the cutter wherebysaid cutter will be kept wet and the tile being cut will also be keptwet by said wet cutter, said guard overhang portion projecting from oneside of the cutter to beyond the axis thereof, and having its sides inspaced relation to the table for work reception therebetween.

4. In combination a slotted work supporting table, a liquid containingtank therebeneath, a rotary cutter rotatably mounted beneath the tableand above the tank and having its lower portion projecting into the tankand its upper portion projecting through the table slot for cutting, andan overhanging combination work and splash guard projecting upwardlyfrom the table adjacent one end of the table slot and including anoverhanging portion extending toward the cutter to beyond the cutteraxis but spaced from the table for confining the splashing from thecutter and returning the discharge to the cutter and to the tank.

In witness whereof, I have hereunto affixed my signature.
